## Common causes

- Scheduled changes are automatically managed by Paddle. You can't change the `scheduled_change` field, other than canceling a change by setting it to `null`.

## Common solutions

- If you want to cancel a scheduled change, use the [update a subscription](https://developer.paddle.com/api-reference/subscriptions/update-subscription) operation to `null` this field.
- Use the [pause a subscription](https://developer.paddle.com/api-reference/subscriptions/pause-subscription), [resume a subscription](https://developer.paddle.com/api-reference/subscriptions/resume-subscription), or [cancel a subscription](/api-reference/subscriptions/cancel-subscription) operations to add scheduled changes to a subscription.
